To all whom it may concern:

Be it known that I, JOHN P. HEBENDAHL, a citizen of the United States, residing at Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Supporting-Brackets for Electric Lights; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to figures of reference marked thereon, which form a part of this specification.

This invention relates to a bracket for raising and sustaining an article, and is particularly adapted for electric lights, the arm taking the weight from the flexible raising or elevating means so that the rope that is usually employed to lift and hold the lamp is released of the strain when the lamp or the object to be held has been secured in the sustaining means.

The invention provides for an arm that is adjustable vertically on the pole to which the lamp is to be attached, and also provides for a casing on the end of the arm which can be made substantially parallel with the ground, or level, no matter how much the depressed.

Another object of the invention is to provide means for varying the distance between the pulley, within the outer casing over which the flexible strand passes, and the sustaining means in the casing so that a double rope for elevating the lamp, or a single rope for the same urpose, can be used. This can be accomplis ed by either moving the pulley toward the sustaining means or forming the sustaining means with means for movin it toward and from the pulley if the puliey is stationary.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a side view showing a part of the bracket and the outer casing. in section. Fig. 2 is a view of a plate with means for attaching the same to the ole and means whereby the bracket can be attached to the plate. Fig. 3 is a section on line 3, 3, in Fig. 1. Fig. 4 is a section'on line 4, 1, in Fig. 1, and Fig. 5 is a section on line 5, in Fig. 1. Fig. 6 is a view of half of the easing with a single rope to support the'electric light. Fig. 7 is a section of the hook employed in the construction shown in Fig. 6. Fig. 8 is a view of half of the casing and a portion of the tube with the pulley stationary and the retaining means arranged so that it is adjustable. Fig. 9 is an enlarged section on line 9, 9. in Fig. 8.

he device is preferably fastened to any usual form of pole 10 against which the plate 11 is bolted or otherwise secured, the plate having a ta )ered and dove-tailed slot 12 into which is tted the two half sections 13 having the dove-tailed portions 15 to fit in the slot 12. The half sections 13 are fastened together by a bolt 11 and serve to support a pulley 16, the axle 17 of which also acts as the pivot for the outer half sections 18 which fit over the half sections 13 and thereby form a knuckle-joint whereby the hollow arm or tube 19 can be swung to adjust it to the desired position irrespective of the pole, that is, it can be made level if the pole is made out of plumb, or if the pole is perpendicular it can be put at an angle to meet conditions. Projecting down from the half sections 13 is a tube '20 which can be dispensed with. but is preferably used to lnore positively guide the rope. The end of the tube 19 can be provided with the'housing 21 which is composed of half sections, as shown particularly in Fig. 1. The housing is connected, by a tie-r0 or rods 22, with the pole so as to more firmly support the weight of the device. Within the housing is arranged a casing 23, which casing is formed of half sections as shown in Figs. 4 and 5, the casing bein adapted to swing in the housing by a suitabFe pivotal connection, such as a bolt, but preferably by having the projections 24., on the lates forming the two sides of the casing, i'itted in the recess portions 25 on the inner face of the housing. This permits the casing to be maintained or adjusted in a horizontal position no matter at what angle the tube 19 is placed, this adjustment being possible by means of the bolt 26 fitting through any of the perforations 27 in the housin and throu h a perforation in the two ha 1 sections 0 the casin the perforations 27 being adapted to be p aced in or out of register with t e perforation in the casing, as will be understood.

The casing is provided with a top portion 28 which forms a cover to prevent snow and rain from entering to rust the parts or to pulled, the pins 37 will bear having a hook 50 on its lower flanges '29 that come together to form a rot the rope, and the casing also has front I closed end, but leaving the opening 30 near the top edge of the front so that the knot 31, of a suitable cord or flexible strand, can be placed in the recess, and the rope or cable passing out through the opening 32 into the casing runs through a pulley 33 having a hook 34 or similar means for supporting the t electric light 35, or any other similar object. t The pulley is provided with side plates 36 j from which project the pins 37, one on each I side, the inner faces of the two side plates j of the casin being provided with a channel that places tie curved surface-38 in the path 7 of the pins 37 as they ride up, and forces the pins away from the pulley 39, over which the rope 40 passes, until the pins snap over 5 the hook 41 and rest in the depression 42 which acts as a sustaining means, and when j the pin snaps over beyond the point 41 it 5 rests against the point 43 which, with the point 41, makes a forked structure with the recess 42 between them into which the pins I 37 rest to sustain the weight. When the t lamp is to be lowered the rope is again against the point 43 of the forked portion, and when they go beyond the oint 43 they will snap over into the channe 44 and then when they are let down they ride overthe surface 45 and pass out of the channel at 46. This I makes a substantially M-shaped passage into and out of which the supporting nieans, which is set in the sustaining means, passes, resting intermediate of its passage when the tension on the flexible strand is relaxed. i The structure previously described is that illustrated in Fig. 1, but I may use but a single rope 40 as shown in Fig. 6, the end of the rope instead of passing over a ulley; and up to the casing again, as in Iig. 1, simply passing over the pulley 39 and having its end passed down throu ha bar 47 which is provided with a soc (et 48 into which the knot 49 of the ro e 40 can be placed, the bar being preferab y s uare and en for supporting the light 35. The square bar 49 has, on each face, a pin 51 so that no matter how the rope twists itwill ride up in the casing with a pair of the pins in position to be engaged by the recess 42. The operation of seating and unseating the supporting means in the restraining means is similar to that shown in Fig. l. The casing is shown in Fig. 6 with the housing left off, and it will be seen from this view that the recess 30, with the opening 52 on its top, forms a means for suspending the casing on a cable or wire over. a passage way, if desired, by running the cable or wire through the recess 30 and through the opening 52, and allowing the top edge 28 of the casing to rest. thereon, It will be noted that if a singlet l l l t I Y To overcome being placed on the inner ,-the side plates of the casing, the slots being made in the shape of an I makes it possible to putstrand or rope. as shown in Fig. 6, were suspended from the position of the pulley in ig. 1, when the supporting means, .suchas the bar 47, was raised it would not be in the path of the curved surface 38 of the casin this and to properly place the pulley, I make the pulley adjustable toward and from the sustaining means by placing the pulley 39, with its axle 40 projecting from each side thereof, .in theslots 41*, a slot surface of each of inverted U so that the alley can be shifted, when the weight is 0 of it, by simply passing itover the cur'ved portion of the slot 41 to bring it'to the desired position, moving it back toward the rear ofthe casing when the double rope shown in Fig. 1 is to be used, and moving it closer up to the sustaining means when the single rope shown in Fig. 6 is used. This any kind of a tool up between the side plates of the casing and take the weight from the pulley and lift the pulley and shift it to its proper place.

Instead of moving the pulley toward the sustaining means I may make the sustaining means movable toward and from the pulley, this being shown more particularly in Figs. 8 and 9. In these views I illustrate the easing 23 fastened to the tube 19 so that it is not adjustable, and Iinake the sustainingmeans with the substantially M-shaped passage therein, formed of two sections 52 which are pivoted at 53 by means of the bolt 54, which bolt can fit in any of the holes 55, these holes being of any number, but it is thought that two sets in line are suflicient to make the adjustment from the pulley 56 to meet the conditions, when either one or two strands of the rope are used to hoist the [weight to be suspended. The sustaining means takes the nature of a latch in Figs. 8 and 9, swinging in its place to move itself when it grasps the supporting means, and snapping into place by means of its pivotal connection, instead of the supported weight being moved out of its path of travel to be can ht.

the structure shown in Fig. 4 I provide the lugs 57, and in the structure shown in Fig. 9 I provide the lugs 58 adjacent to thetop edge of thepulleys in each of the respective constructions so that the rope cannot ride from the pulley and get jammed between the pulley and the casing, and is also held in place so as to make the operation of the device easy.
